Corsair RM750x or RM850x PSU Recommendation


I bought the prebuilt pc from Techfast, R5-3600 RTX 3060 Ti. I was told by my friends that I should invest into a better psu as a bad psu has the potential of exploding, which I dont want to happen. I've noticed that the Corsair rm series is quite similar in price to the rmx series, and since rmx series is better quality? am planning to buy one. However its only roughly $40 difference and wasn't sure if the $40 is worth for my build to get an extra 100W? (On a really tight budget and new to computers.. so the $40 matters to me… but willing to invest the bit extra if worth)

Below is the list of parts I found from

CPU - AMD Ryzen 5 3600 3.6 GHz 6-Core Processor
Motherboard - Gigabyte B450M DS3H Micro ATX AM4 Motherboard
Memory - PNY XLR8 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory
Storage - Kingston A400 240 GB 2.5" Solid State Drive
Video Card - PNY GeForce RTX 3060 Ti 8 GB UPRISING Video Card
Case - MSI MAG FORGE 100R ATX Mid Tower Case
Power Supply - Kingwin MK 750 W ATX Power Supply

Only plan to use it for gaming and video editing (Premiere/final cut)

Q1: Is it worth?
Q2: If I were to upgrade in like 5-10 years by building my own pc is it better to get the rm850x?
What are your suggestions? (Quite clueless right now…) Thanks~



    750w is more than enough. Even the RTX 3080 only recommends a 750w PSU.

    If you’re running an OC on the CPU, normal amount of RAM, fans and drives, you won’t have a problem on 750w.

    If you’re really tight on budget, the x does benefit from Japanese capacitors and a better fan but any family of 650/750/850 RMX will suffice for your PC specs so I’d just wait for a sale on any one of those three.


    uMart have a sale on this weekend on selected PSU's
    I prefer the EVGA PSU's, I have a 1200W P2 in my rig
    It is 7 years old, it comes with a 10 year warranty
    It looks like Johnny Lucky has taken over from Johnny Guru (he is a legend)


    fyi, theres a bad batch of rm750s going around.
    be prepared to return for DOA.


      RM750 or RM750x?




          Yeah I've got a Corsair RM750x 750W which may have just blown up a heap of equipment, avoid
